I have nothing witty to say. Here's something I prepared earlier.

Mlle C: i'm assuming it's safe to bother you while you're twiddling your thumbs
titania fae: Oh, I don't know. Twiddling takes a lot of concentration. I might drop a thumb.
Mlle C: and that would be a crisis of massive proportions
titania fae: It would. They roll under the furniture and you can never find them again.
Mlle C: and opposable thumbs are so useful
titania fae: They are. People should sell spares.
Mlle C: yeah, but can you imagine the prices? supply couldn't possibly meet demand
titania fae: It'd be a status symbol. How many thumbs do you have?
Mlle C: oh yes. and rappers would have to have platinum plated ones
titania fae: On large chains around their necks.
Mlle C: yes
Mlle C: with diamonds on them
